My invention relates to rail anchors and has for its principal objectthe provision of a one-piece anchor device of improved. construction,whereby the device is tensioned during its application to a rail so asto exert a strong resilient grip, both vertically and transversely ofthe rail base.

Another object is to provide ail-anchor having thecharacteristics abovereferred to, which can be applied by driving it transversely of: therail base from one side thereof, and which is so constructed that ananchor of one standard size may be applied to rails of dilierent sizes.

anchor construction which exerts both v-er tical and transverse springgrips on the base of the rail, which maintains the maximum tension towhich it is subjected during its application, and. which increases thegrip of the device both vertically and transversely of the rail when thedevice is subjected to creeping pressure.

The invention consists of such further new and improved construction aswill be hereinafter described and claimed for carrying out the abovestated objects and such other objects as will appear from the follow ingdescription of the embodiment shown in the accprnpanying drawing.

The embodiment of my invention shown larly disposed U-shaped jaw 15,thefree Another object is to provide an improved distance between theshoulder. 11 and theapplied, so that it is necessary to tension therailroad rail. The straight body portion 10 .5 of the bar normally bearsagainstthe' bot-9 tom surface of the rail and is bent down- 5 wardly andupwardly topro'vide a loop 14. The said loop is so positioned withrespect to the shoulder portion 11 that the upstand'e ing arm 14' ofagainst the vertical edge of the rail base at the opposite side of therail. The up standing arm 14 is bent to provide an angu r end 16 ofwhich is bent, downwardly wto x;

provide a vertical arm 14* which. aligns with the arm 141.- The arms 14,14* are disposed on opposite sides of the body por tion 10, so as tocontact with. the edge of the rail base at points on opposite sides ofthe body. This arrangementserves to hold the straight body portion 10 ofthe anchor in a position substantially at right'angles to thelongitudinaledges' of the rail base so that the engagement of theshoulder ll with the opposite edge of the rail base will be at it apoint substantially midway between the; said arms 14, (14: The jawportion 15' so formed with respect to the body portion 10 of the anchorthat the verti'rsl dis tance between the jaw and said body per tion,when the anchor is free of the rail, is normally less than thethickness'of the rail base at the point engaged by said mem bers whenthe anchor is in itsapplicd posi tion, whereby -it is necessary to forcethe said jaw and body portion apartwhcn driv mg the anchor to its.applied-position. Tli e' upstanding arms 34-. ll" when the anchor isfree of the rail, is norn'mlly less than the width of the rail base towhich the device loop portion of the anchor when forcing the shoulder 11over the edge oi: the-rail base. i

In applying the anchor to a rail, the jaw",

portion 15 is hooked over one base flan e of the rail in a positionadjacent one ot the cross ties 17, so that one of the arms 14 lel,will'bear against the vertical face of Q the cross tie. The anchor isthen=driven;- from the initial position shown in dotted. lines in Fig.2, tothe applied'po sitiofi b I striking the loo portion of the anchor 1,1 asledge. The roe'of theblow against the loop portion body portion't-h the loop normally bears.

- 15 upon the inclined surface vice versely of the rail until theshoulder pcrtion 11 clears the edge 18 of the rail base, whereupon thesaid shoulder snaps into, en-

agernent with the vertical face of the base ange, The transversemovement of the body portion 10 of the anchor reduces the diameter ofthe loop 13 andtherebyt tensions the anchor so that the upstanding arms14:, 14* and the shoulder 11 exert a streng spri-pg grip on oppositeGdgeSlOf the rail base. The hammer blows against the loop, in additionto driving; the body portion transversely of the rail, force the jaw ofthe rail base.

lhis movement of the jaw tends to f further. tension the loop portion ofthe anchor so as to exert a strong spring grip of the jaw and bodyportion 10 upon the top and. bottom surfaces respectively, of the baseflange l2 of the rail base. The tendency which the spring loop has toexpand to theposition from which it was sprung, exerts a strong springpressure through the 'jaw 15 and body 10, against the upper and lowersurfaces, respectively, of the rail'base, and exerts a strong springgrip through the arms 14, 14 and the shoulder 11 horizontally across therail base. The spaced arms 14,14 hold the body portion 10 and theshoulder 11in a centralized position'with reference to the said arms,and at sub-- stantially right angles to the length of the rail.

Niththe arrangement shown; any creep ing pressure tending to move theshoulder 11 nearer the tie, will increase the distortion of the loop 13and thereby increase the grip of the device on the rail. The dependingarms 14: and 1d are so positioned with respect to thebody portion'of theanchor that the anchor may be applied in its initial positiqn with oneof. the said'arms in engagement with a cross tie, there being sufficientclearance between the cross tie and the upper portion of the loop 13 topermit the anchor to-be driven to its applied position without danger ofstriking the cent tie. The relatively large loop 13 pro vides maximumresiliency whereby the dey be adjusted to the base flange of rails 0various ,widths and thickness, without danger of impairing theresiliency of the anchor.
